CORPORATION OF DELAWARE OIL-DISPENSING APPARATUS Application filed October as, 1925. Serial No. 64,311.

This invention relates to oil dispensing apparatus and more particularly to visible display attachments for oil delivery pumps wherein provision is made for ready comparison of the oil delivered with sample specimens contained in sealed transparent containers.

One of the objects of the invent-ion is to provide an attachment for pumps for displaying sealed transparent containers hold ing sample specimens of the liquid which is offered for sale in close proximity to a visible stream of the liquid as it is actually dispensed.

Another object of the invention is to provide a visible display attachment wherein the sample container can be readily removed and new ones inserted when the oil dispensed from the pump is changed.

Another object of the invention is to provide a visible display attachment for dispensing pumps which can be quickly and easily connected to or removed from the discharge pipe of a pump.

Still another object is to provide an attachment which is pleasing in appearance and which can be easily assembled and disassembled.

Other objects, features and advantages of the invention will be readily apparent from the following description thereof and illustrated in the accompanying drawings in which Fig. 1 is a view in side elevation of an attachment embodying my invention.

Fig. 2 is a partially sectional view of the apparatus shown in Fig. 1.

Fig. 3 is a sectional plan view taken on the line 33 of Fig. 2.

Fig. 4 is a sectional plan view of a modified form of my invention taken on a line corresponding to 33 of Fig. 2. g 1

F 5 is a sectional plan view of a further modification of my invention taken on a line corresponding to 33 of Fig. 2.

Referring to the preferred form of my invention as shown in sectional elevation in Fig. 2, represents the discharge pipe of an oil pump (not shown), one end of which pipe connects with the pump while the other end is exteriorly threaded for attachment in one end 11 of a substantially inverted U-shaped pipe section 12, the opposite end 13 of which is formed with a flange 14;.

A cover plate or head 15 having a centrally disposed orifice 16 is secured to the flange 1'1 by means of bolts and nuts 17 A washer 18 is disposed between the flange 14: and the head 15 to form a liquid tight seal. The head 15 is formed with a centrally disposed downwardly projecting annular flange l9 and with annular recesses 20 in its lower face on opposite sides of the flange 19.

A base member 21 formed with a centrally disposed downwardly projecting boss 22 is disposed directly beneath the head and spaced therefrom, being maintained in spaced relation by means of elongated bolts 23 and nuts 24:, the bolts each being formed near their extremities with spacer washers 25. The boss 22 is formed with an internally threaded orifice 26 to which a delivery boss 27 or the like can be readily connected. The base 21 is formed with a centrally disposed upwardly projecting flange 28 and with a pair of upwardly extending cup shaped tubular members 29 each of which is formed with an upper peripheral recess 30 constituting a seat for a sealed transparent container 31 which may conveniently take the form of an ordinary glass bottle having a neck 32 of restricted diameter and a lip 33. The bottle is sealed by means of a stopper 34.

A cylindrical shaped cap or sleeve 35, open at one end and formed at its open end with an inner peripheral groove 36, is disposed over the neck of each of the bottles 31 and a coil spring 37 is positioned within the cap so as to be compressed when the cap is drawn down over the neck of the bottle, one end of the spring being seated on the lip of the bottle.

An elongated tubular member 38 of glass or other transparent material is cemented at its ends into cap-shaped members 39 and 10 respectively, in order to prevent the glass from being chipped or broken at its ends, the

cap members being of a size and configuration to fit withln the flanges 19 and 28 and each havin an o enm in its end 1n axial 1l1'll I a '-1 b .c 1 1 a ment W113i). the hole or the tune. l't hen so poice iii)

. oil flows with respect to the sample bottles is sitioned the tubular member forms a continuous line of flow between the U-shaped pipe 7 section 12 and the boss 22 which, as has already been stated, is connected to a delivery pipe.

The method of assembly is as follows:

The head 15 is first bolted to the flange 14. The end oithe tubular member 38 to which the cap 40 has been cemenated is positioned,

within the flange 28 of the base 21 while its upper end having the cap 89 is inserted within the flange 19. The bolts 23 are then placed in position and the nuts 24: screwed up to hold the base against the spacer washers and in position with res acct to the head. The glass bottles are then placed in position by drawing he cap 35 down over the neck of the bottle against the pressure of the spring 36 so that with th base of the bottle seated in the recess 29, the cap 35 will slide in under the head 15 the attachment is secured. ll hen the pump is operated the oil will flow in the direction indicated by the arrows, hrst upwardly through the pipe 10 then through the inverted U-shapec pipe 12 and downwardly through the transparent tube 38. Thus a stream of fiowin oil as actually being dispensed from the pump is displayed conspicuously l etween the two sample bottles of oil through all of which the light can shine, and the purchaser is in a position to readily determine whether or not the oil being dispensed from the pump conforms in color to that of the samples displayed in the two sample bottles.

In the modified forms of my invention as illustrated in Figs. 4: and 5 the principle of operation issubstantially the same, but the arrangement of the pipe through which the somewhat dii'lerent. As shown in Fig. 4 the sample bottles l1 are positioned somewhat nearer together than in the apparatus shown in Fig. 2 and the transparent tube 42 through which the oil actually flows is. positioned slightly behind or in front, depending upon whether the apparatus is viewed from one side or the other, of the sample bottles. Thus, from practically any angle from which the apparatus may be viewed, any difference in the color or the oil flowing through the tube 41 will be readily detected by reason of t 1e contrast.

In the apparatus shown in Fig. 5 a single sample bottle is employed and the sample bottle and the elongated transparent tube are arranged concentrically, the one within the.

other, so that any diii erence in color between the oil belng dispensed and that in the sample tube will be indicated by either a light or dark streak in the center of the tube.

Apparatus of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be practiced,but the inventive thought upon which this application is based is broader than the illustrative embodiment thereof, and no limitations are intended other than those imposed by the appended claims.

What I claim is:

1. A visible display attachment for pumps comprising a cover plate or head having a centrally disposed, opening, a base spaced from said head and having a centrally disposed opening in axial alignment with the opening in the head, a transparent tubular membermounted in the openings in said cover plate and base and communicating at one end with the discharge pipe of the pump, and a-transparent sample container removably secured between said cover plate and base adjacent to the transparent tubular member enabling a ready comparison between the liquid being pumped and he standard sample in the sealed container.

2. A visible display attachment for pumps comprising a cover plate adapted to be secured to the discharge pipe of thepump and formed with an opening adapted to register with the open end 01"- the discharge pipe, a

base spaced from said cover plate and formed with an opening to which a delivery hose may be secured, a transparent tubular member disposed between the cover plate and base for delivering the pumped liquid from the dischar e )i ac to the o ienin in the base and a sealed transparent sample container removably secured between the cover plate and base and closely adjacent to the tubular member enabling a ready comparison between the liquid being pumped and the standard sample in the sealed container.

3. A visible display attachment for pumps comprising a cover plate adapted to be secured to the discharge pipe of the pump and formed with anopening adapted to register with the open end of the discharge pipe, a base spaced from said cover plate and formed with an opening to which a delivery hosemay be secured, a transparent tubular member disposed between the cover plate and base for delivering the pumped liquid from the discharge pipe to the opening in the base, means secured on the opposite ends of the tubular member to prev'ent'the breaking thereof, and a sealed transparent sample container removably secured between the cover plate and base and closely. adjacent to the tubular member enabling a ready comparison between the liquid being pumped and the standard sample in the sealed container.

In witness, whereof I have hereunto set my hand and seal. this 20th day of October, 1925.
